Abstract: ABSTRACT      The disclosure describes a system of connecting a plurality of independently operable data processor systems to obtain a substantial increase in power and flexibility.  Each of the pluralities of independently operable systems has its own memory, and the respective memories are accessible by a data transfer controller connected to each memory by a common bus.  Since all data transfer activity is controlled by the data trans-fer controller, there is no need for any communication between respective independently operable data processor systems, and in one embodiment of the invention, the data transfer controller has its own separate memory to store data temporarily as it becomes available in one memory which will be needed by another data processor system.

Abstract: Abstract An apparatus for minimizing the spillover signal from the transmitter to the receiver in a same frequency repeater includes a mechanism for generating a receiver first injection signal carrying the modulation component of the transmitter signal, and a first mixer for mixing the received signals and the first injection signal to produce a first IF signal having one unmodulated IF component signal and another modulated IF component signal.  A correlation and cancellation circuit is utilized to cancel the unmodulated IF component signal. A mechanism is provided for generating a second injection signal which carries the modulation component of the transmitter signal.  A second mixer mixes the first IF signal and the second injection signal to produce a second IF signal such that the modulation component of the spillover signal is substantially cancelled.  Time synchronization mechanisms are preferably provided to adjust the phase of the modulation component of the transmitted signal as carried by the first and second injection signals such that it arrives at the first and second mixers in phase synchronization with the modulation component of the spillover signal.  This invention also contemplates a method for canceling the modulation component of the spillover signal.

Abstract: ABSTRACT OF THE DISCLOSURE           Floor covering, such as carpets or other covering materials for residential and general furnishing, are fixed to a floor or other surface by means of an applied bonding layer.       Embedded into the bonding layer are adhesive particles which are made chemically passive and the cohesive forces of which are greater in the thermoplastic state than their adhesive forces and which are converted, only after the carpet has been laid and adjusted in position, from their non-adhesive state into a malleable tacky phase of the layer as a result of the effect of temperature, after which a firm bond is produced in a cooling phase as a result of the lowering of this temperature.  Alter-natively, the bonding layer may be provided by a separate inter-layer.

Abstract: ABSTRACT OF THE DISCLOSURE         There is provided a protein-free and low sodium high stability fat emulsion which comprises on a solid basis, 10 to 75% of an edible fat having an average particle size of 4 microns or less, 0.1 to 3% of an emulsifier, 8 to 20%          (based on the fat) of an edible hydrated, substantially undextrinized, lipophilic starch in submicroscopic particle size, and the remainder of the solids being principally a filler.  The emulsion may be either a water emulsion or a dry powdered emulsion.  The emulsion is prepared by mixing the fat, emulsifier, starch and filler in water.  The mixture is cooked at an elevated temperature if the starch has not been previously cooked to hydrate starch.  The mixture is sheared such that the fat  is divided into an average particle size of 4 microns or less and the starch is dispersed in submicroscopic form.  The sheared mixture is then dried to a moisture content of 7% or less.  The starch may be dispersed to the submicroscopic particle size either prior to or during the process.

Abstract: TITLE          Stable AN/Emulsion Explosives and Emulsion for Use Therein ABSTRACT OF THE DISCLOSURE         Explosives that are sensitized blends of a water-in-oil emulsion and AN particles, such as AN or ANFO prills, have improved stability when their structure hinders the loss of water from the aqueous emulsion phase and transportation of such water across the oil phase to the AN particles.  Use of an anionic emulsifying agent comprising a fatty acid salt, e.g., as formed in situ during the formation of the emulsion, is the preferred way of forming such a blend-stabilizing structure.  Emulsion/ANFO and emulsion/AN blends stabilized in this manner make satisfactory storage-stable packaged products. Emulsion/AN blends made with a new low-viscosity emulsion containing essentially all of the oil required to oxygen-balance the blend and a proportionately larger amount of anionic emulsifying agent to stabilize the emulsion structure constitute preferred bulk products owing to their greater adaptability to pumping.  Pumping the stabilized blends through an annular stream of aqueous lubricating liquid is advantageous.

Abstract: ABSTRACT OF THE DISCLOSURE An information recording medium for use with focused laser beams modulated with recorded information signals comprising a substrate having a recording layer composed of at least two layers, the first being formed on the substrate and the second being formed over the first.  The substrate and the first layer have the property of high transmittance to laser beams and the second layer is composed of a metal which is predominantly a low melting metal capable of absorbing the laser beams and readily forming an alloy with the material of the first layer, the thickness of the first layer being such that the reflectance of the laser beams entering from the side of the substrate is lowered by the interference effect caused by repetitive multiple reflections.  The metal of the second layer is thus alloyed to the first layer due to the focused irradiation of the laser beams from the substrate to the recording layer, changing the conditions for the multiple reflections and changing the reflectance in the recording layer as viewed from the substrate, thereby carrying out the recording of the information.

Abstract: ABSTRACT OF THE DISCLOSURE          Genetic analysis and modification of Pseudomonas bacteria is accomplished using a suicide plasmid which includes genes for replication in a narrow range of host cells and genes for conjugal transfer of the plasmid into a broad range of bacterial hosts, including Pseudomonas.  The genetic donor is E coli and the plasmid carries a transposon having at least one antibiotic resistance marker, e.g. kanamycin resistance or tetracycline resistance, conferring thereon an antibiotic resistance not found in the Pseudomonas host or in the remainder of the suicide plasmid.  The suicide vector is constructed and introduced into E coli cells, in which it replicates. Then it is introduced into Pseudomonas cells by conjugal transfer, whereupon the transposon inserts into the DNA of the recipient, deactivating or altering the activity of a gene therein, whilst the residue of the vector is eliminated and does not replicate.          By this means, the operative symbiotic genes in the Pseudomonas may be identified, by comparison of the genetic behaviour of the modified Pseudomonas cells so formed with wild type Pseudomonas cells.
